Conservative historian Andrew Bacevich discusses his provocative book *The Limits of Power: The End of American Exceptionalism*. Bacevich joins Charles Sennott, founder of the online news service GlobalPost, to discuss the challenges the Obama administration faces in Afghanistan. Written in the days leading up to the 2008 presidential election, *The Limits of Power* asks us to take a step back from the policies that have not served us well, and calls for a return to respect for power and its limits; aversion to claims of exceptionalism; skepticism of easy solutions, especially those involving force; and a conviction that Americans must live within their means. Only a return to such principles, Bacevich argues, can provide common ground for fixing America's urgent problems before the damage becomes irreparable.
